Detailed Implementation

[0026] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0027] See Figures 1-6 This is a schematic diagram of the structure of the present invention, a device for rinsing and separating waste plastic film, including a rinsing chamber placed on the ground. The rinsing chamber is used to carry the rinsing operation of waste plastic film, providing a stable working space for the entire rinsing and separation process, and realizing the initial separation of debris from the plastic film. A cleaning device is installed at the top of the rinsing chamber. The cleaning device is used to actively clean the waste plastic film in the rinsing chamber. Through mechanical action, the surface of the plastic film is scrubbed to remove stubborn debris such as mud and weeds attached to the surface of the plastic film, thereby improving the cleanliness of the rinsing. A plastic film crushing device is installed on the right side of the top of the rinsing chamber. The plastic film crushing device is used to crush the waste plastic film to be processed, breaking large pieces and tangled waste plastic film into smaller pieces, which facilitates the removal of debris during the subsequent rinsing process. At the same time, it increases the contact area between the plastic film and the cleaning medium and the cleaning device, thereby improving the cleaning efficiency.

[0028] The inner wall of the rinsing chamber is equipped with cleaning nozzles 17 evenly distributed. The cleaning nozzles 17 are used to spray cleaning media into the rinsing chamber. Through the impact of high-pressure water flow, the debris on the surface of the mulch film is further washed away. At the same time, the cleaning media in the rinsing chamber is driven to flow, forming a stirring effect, so that the debris can be quickly separated from the mulch film and settle. The nozzles on the inclined tubes of the cleaning nozzles 17 are angled towards the cleaning roller 5, which can specifically wash the mulch film on the cleaning roller 5 and improve the cleaning targeting. The nozzles on the straight tubes of the cleaning nozzles 17 are set vertically, which can thoroughly wash the mulch film in different positions in the rinsing chamber and avoid cleaning blind spots. A drain outlet is provided at the bottom of the rinsing chamber to discharge the wastewater containing debris in the rinsing chamber, providing a channel for subsequent debris separation.

[0029] The sewage outlet is connected to a debris separation cylinder 12, which is used to receive the sewage containing debris discharged from the sewage outlet and provide installation and working space for the debris filter element to separate sewage from debris. The debris filter element is inserted inside the debris separation cylinder 12 to filter the sewage containing debris, intercepting debris such as mud, weeds, and mulch film fragments in the sewage inside the filter element, thereby purifying the sewage and facilitating subsequent recycling. The top of the debris separation cylinder 12 is connected to a circulation component, which is used to extract the purified water in the debris separation cylinder 12 and transport it to the cleaning nozzle 17 to realize the recycling of the cleaning medium, save water resources, and reduce equipment operating costs. The circulation component is connected to the cleaning nozzle 17 to ensure that the purified water can be smoothly transported to the cleaning nozzle 17 and continuously provide cleaning medium for rinsing operations.

[0030] A plastic film support plate 18 is fixed on the left side of the rinsing chamber. The plastic film support plate 18 is used to receive the plastic film after rinsing. At the same time, a permeable mesh plate is set on the plastic film support plate 18 to allow the residual water on the surface of the plastic film to seep out quickly, reducing the water carried by the plastic film. An adjustable water squeezing component is set on the plastic film support plate 18 to squeeze out the water after rinsing, removing a large amount of residual water on the surface of the plastic film, which facilitates the subsequent collection, drying and reprocessing of the plastic film.

[0031] The rinsing chamber includes a rinsing tank support 2 placed on the ground. The rinsing tank support 2 supports the rinsing tank 1, allowing the rinsing tank 1 to be placed stably on the ground and preventing it from tilting or shaking due to the presence of cleaning media and mulch film. The rinsing tank 1 is fixed on the rinsing tank support 2. The rinsing tank 1 is used to hold the cleaning media and waste mulch film to be treated, providing a closed space for rinsing and cleaning the mulch film. The inner wall of the rinsing tank 1 is provided with a slope that extends to the drain outlet. The slope guides the debris and wastewater containing impurities in the rinsing tank 1 towards the drain outlet, preventing debris from accumulating at the bottom of the rinsing tank 1, ensuring smooth drainage, and improving the efficiency of debris separation.

[0032] The cleaning device includes a motor bracket 3 fixed to the outer wall of the rinsing tank 1. The motor bracket 3 is used to fix the drive motor 4 and provide stable installation support for the drive motor 4. The drive motor 4 is fixed on the motor bracket 3. The drive motor 4 is the power source of the cleaning device and provides power for the rotation of the cleaning roller 5. The rotation of the output shaft drives the cleaning roller 5 to rotate synchronously. The output end of the drive motor 4 is fixed to the cleaning roller 5. The cleaning roller 5 is used to directly contact the waste plastic film. Through the mechanical friction during the rotation process, it scrubs the surface of the plastic film and rubs off the debris attached to the plastic film. At the same time, it drives the plastic film to move in the rinsing tank 1, so that the plastic film can fully contact the cleaning medium and the water flow of the cleaning nozzle 17. The shaft of the cleaning roller 5 is set on the rinsing tank 1 through a bearing seat. The bearing seat is used to support the shaft of the cleaning roller 5. Multiple plastic film pressure plates are set on the outer wall of the cleaning roller 5 to enhance the friction between the cleaning roller 5 and the plastic film, improve the cleaning effect, and prevent the plastic film from floating or shifting during the impact of water flow and the rotation of the cleaning roller 5, ensuring that each piece of plastic film is thoroughly cleaned.

[0033] The plastic film crushing device includes a feed hopper 6 fixed above the right side of the rinsing tank. The feed hopper 6 receives the waste plastic film to be crushed, guiding it accurately between two crushing rollers 7 to prevent it from falling outside the equipment. It also prevents film fragments from splashing during the crushing process, ensuring a clean working environment. Two crushing rollers 7 are rotatably connected to the feed hopper 6. The two rollers 7 cooperate, generating compressive and shearing forces through relative rotation to crush large, tangled pieces of waste plastic film into smaller pieces, facilitating subsequent rinsing operations. The two crushing rollers 7 are connected by a drive gear 8 and a driven gear 9, which enable synchronous counter-rotation of the two rollers 7, ensuring a smooth and uniform crushing process and preventing spillage. In the event of mulch film jamming, the driving power is simultaneously transmitted so that the two crushing rollers 7 can obtain sufficient crushing torque. The drive gear 8 and driven gear 9 are equipped with gear guards 10. The gear guards 10 are used to protect the drive gear 8 and driven gear 9, preventing the gears from being caught in debris and dust during rotation, avoiding gear wear and jamming, and ensuring the personal safety of the operator by preventing them from being scratched by the rotating gears. The drive gear 8 is connected to a crushing roller driver 11, which is the power source of the mulch film crushing device. It provides power for the rotation of the drive gear 8, thereby driving the two crushing rollers 7 to rotate synchronously, realizing the crushing operation of the mulch film. The output speed can be adjusted according to the thickness and hardness of the mulch film to ensure the crushing effect.

[0034] The debris filter element includes a debris filter cartridge 13 inserted into the debris separation cylinder 12. The debris filter cartridge 13 is used to filter debris in wastewater containing impurities. Its cylinder wall is provided with fine filter holes, which can intercept impurities such as mud, weeds, and mulch film fragments, while allowing purified water to pass through, thus achieving the separation of wastewater and debris. A filter cartridge cover 14 is threadedly connected to the left side wall of the debris filter cartridge 13. The filter cartridge cover 14 is used to seal the end of the debris filter cartridge 13 to prevent debris from overflowing from the end of the filter cartridge. At the same time, the threaded connection makes it easy to disassemble. When too much debris accumulates in the debris filter cartridge 13, the filter cartridge cover 14 can be unscrewed to clean the debris in the filter cartridge, ensuring that the filtration effect is not affected and extending the service life of the debris filter element.

[0035] The circulation assembly includes a circulation pump 15 connected to the debris separation cylinder 12. The circulation pump 15 is used to extract the purified water from the debris separation cylinder 12 and provide power to make the clean water flow in the circulation system. The circulation pump 15 is connected to a delivery pipe 16, which is used to deliver the clean water extracted by the circulation pump 15. The purified clean water is delivered from the debris separation cylinder 12 to the cleaning nozzle 17, providing a stable water flow to the cleaning nozzle 17. The delivery pipe 16 is connected to the cleaning nozzle 17 to ensure that the clean water can smoothly enter the cleaning nozzle 17 and be sprayed into the rinsing chamber through the nozzle, realizing the recycling of the cleaning medium and reducing the waste of water resources.

[0036] The dewatering assembly includes a dewatering roller bracket 19 adjustable on the outer wall of the mulch film support plate 18. The dewatering roller bracket 19 supports the dewatering roller 20 and can adjust the height and position of the dewatering roller 20 according to the thickness of the mulch film to ensure that the dewatering roller 20 can make close contact with the mulch film and improve the dewatering effect. The dewatering roller 20 is rotatably connected to the dewatering roller bracket 19. The dewatering roller 20 is used to contact the mulch film. Through the squeezing force during the rotation process, the residual water on the surface of the mulch film is squeezed out, reducing the water carried by the mulch film and facilitating subsequent processing. A dewatering roller drive component 21 is provided at the shaft of the dewatering roller 20. The dewatering roller drive component 21 provides power for the rotation of the dewatering roller 20, driving the dewatering roller 20 to rotate synchronously, making the dewatering process continuous and efficient. At the same time, the rotation speed of the dewatering roller 20 can be adjusted to match the conveying speed of the mulch film to ensure uniform and thorough dewatering.

[0037] A permeable mesh is provided on the mulch film tray 18. The permeable mesh is used to accelerate the seepage speed of residual water on the surface of the mulch film, prevent water from accumulating on the mulch film tray 18, and prevent the mulch film from sticking to the tray, which facilitates the transportation of the mulch film. The bottom end of the mulch film tray 18 is connected to the transportation pipe 16 through a pipe. This pipe is used to transport the water that seeps from the mulch film tray 18 to the transportation pipe 16 and re-enter the circulation.

[0038] When using this invention:

[0039] First, the waste plastic film to be processed is fed into the feed hopper 6 of the plastic film crushing device. The feed hopper 6 guides the plastic film into the space between two crushing rollers 7. At this time, the crushing roller driver 11 starts and drives the drive gear 8 to rotate. The drive gear 8, through meshing with the driven gear 9, drives the two crushing rollers 7 to rotate synchronously in opposite directions. The large and tangled waste plastic film is crushed into smaller pieces by the squeezing and shearing forces between the two rollers. The crushed plastic film falls into the rinsing tank 1 of the rinsing chamber. After the plastic film enters the rinsing tank 1, the washing device is activated. At the start of operation, the drive motor 4, fixed to the motor bracket 3, starts, driving the cleaning roller 5 at the output end to rotate. The mulch film pressure plate on the outer wall of the cleaning roller 5 presses the mulch film, making the mulch film tightly adhere to the surface of the cleaning roller 5. The mechanical friction generated by the rotation scrubs the surface of the mulch film, removing stubborn impurities. At the same time, the cleaning nozzles 17, evenly distributed on the inner wall of the rinsing tank 1, spray the cleaning medium. Among them, the inclined nozzles are directed towards the cleaning roller 5 to specifically rinse the mulch film, and the straight nozzles are set vertically to achieve comprehensive rinsing. The high-pressure water flow further washes away impurities and drives the cleaning medium to flow. This process allows debris to quickly detach from the mulch film and settle. Wastewater containing debris flows through the drain at the bottom of the rinsing tank 1 into the connected debris separation cylinder 12. The debris separation cylinder 12 receives the wastewater containing debris and provides working space for the debris filter elements. The debris filter elements 13, inserted into the debris separation cylinder 12, intercept soil, weeds, and other debris through the fine filtration holes in the cylinder wall. The purified water is drawn out by the circulation pump 15 of the circulation component and transported to the cleaning spray pipe 17 via the conveying pipe 16, realizing the recycling of the cleaning medium. The rinsed mulch film is then transported... The film is placed on the film tray 18 on the left side of the rinsing chamber. The permeable mesh on the film tray 18 accelerates the leakage of water from the surface of the film. The leaked water flows through the pipe at the bottom of the film tray 18 into the conveying pipe 16 and re-enters the circulation system. At the same time, the water squeezing device on the film tray 18 starts to work. The water squeezing roller drive 21 drives the water squeezing roller 20 to rotate. The squeezing force squeezes out a large amount of water remaining on the surface of the film, ensuring that the film is dry for subsequent collection, drying and reprocessing. This completes the rinsing and separation of impurities from the waste film.
